Given:
The radius of the sphere = 4 cm
To find:
The area of the sphere.
Solution:
We were supposed to find out the area of the sphere whose radius is 4 cm.
We know that the formula to calculate the area of a sphere with a radius of "r" will be:
= 4πr²
Thus on the substituting the given value of radius into the formula, the required area of the sphere will be:
= 4π× (4)²
= 64π cm²
= 201.06 cm²
Thus the required area of the sphere will be 201.06 cm².
